15 páginas, 4 figuras, 4 tablas.-- Scientific Council Meeting A ramdomly stratified bottom-trawl survey was realized in the Flemish Cap (NAFO Div.3M) in July 1983. The stomach contents of three species were studied: 320 of American plaice (Hippoclesoides platessoides), 293 of redfish (Sebastes llarinus) and 463 of cod (Gadus morhua). The cod specimens were classified taking into account age groups; in the case of other species by length classes. The food items, the prey occurrence index and the diversity index were determined too. The Schoener overley index was calculated to study the intraspecific diet overlap in cod and the interspecific diet overlap between the three species. The relation between predator size (cod) and prey size (redfish) was also studied. Peer reviewed
